Inflammation has been recognised to both decrease beta cell insulin secretion and increase insulin resistance. Circulating cytokines can affect beta cell function directly leading to secretory dysfunction and increased apoptosis. These cytokines can also indirectly affect beta cell function by increasing adipocyte inflammation.The resulting glucotoxicity and lipotoxicity further enhance the inflammatory process resulting in a vicious cycle. Weight reduction and drugs such as metformin have been shown to decrease the levels of C-Reactive Protein by 31% and 13%, respectively...

OBJECTIVE: To explore the exact role of ghrelin in glyco- and lipo-metabolism. METHODS: We compared the levels of ghrelin mRNA in gastric tissue, ghrelin in gastric tissue and plasma among LETO rats( non diabetes, n=10), OLETF rats( type 2 diabetes, n=10), OLETF/M rats( OLETF rats managed with Metformin at the dose of 100 mg/kg weight, n=10) and OLETF/F rats( OLETF rats managed with Fenofibrate at the dose of 20 mg/kg weight, n=10). The levels of ghrelin mRNA were tested by Northern blotting, and the ghrelin content in gastric tissue and plasma detected by RIA...

The first part of the paper deals with the relationship between two inhibiting factors of the complex enzyme cascade regulating fibrinolysis, namely plasminogen activator inhibitor type-1 (PAI-1) and lipoprotein(a) (Lp(a)). Blood concentrations of Lp(a), PAI-1 antigen (PAI-1 AG) and activity (PAI-1 AT), and the main parameters of lipo- and glyco-metabolic balance were studied in 80 type II diabetic patients. Roughly hyperbolic patterns have been found between PAI-1 and Lp(a). Negative statistically significant linear correlation can be elicited when Log PAI-1 AG and Log PAI-1 AT values are plotted versus Lp(a) values, the first one being particularly tight...
